DISPENSING DEVICE Application 'fiIed' July 13,

This invention relates to. a dispensing "apparatus, and has for an object to provide improved means" for dispensing the contents of collapsible tubes. I I j A further object of the invention is to provide a structure adapted to collapse a. collapsible tube progressively, and includes improved means for conducting the exuded material to the point of use. I

A further object of the in-ventionisto -provide a structureembodying adja'cently journaled rollers between which a collapsible tube is successively wound, with improved means making contact with the nipple end of the collapsible tube followingsuch nipple and end in the progressive rolling and conducting of the exuded materialto the point of use. I a

The invention, therefore, comprises a structure upon which is journaled adjacent rollers, with means for rotating the rollers, such rollers being properly proportioned to receive therebetween a collapsible tube, with an upright having a follower movable'thereon carrying a cap covering over the nipple or other end section of the tube,'with a conduit for conducting the material, and a closure for the-conduit. I I

The invention is directed to other objects, and possesses other features of novelty and advantage, some of which, together with the foregoing, will be hereinafter more fullyset ,forth. I In the drawings: 7 Figure 1 is a view of the device inside elevation, parts being broken away, V

The improved dispensing apparatus, which i forms the subject matter of this application,

theend by collapsing the tubeat theopposite end, or *interniediatethe ends. The present structure comprises "a plate 17,

ing therefrom,such plates or :lbrackets being connected at their ends opposite the =plate'17 bya cross bar 19; I a I I The side brackets 18 serve for -journaling carrying rollers 22 and 23." These rollers 22 i that the lower end of the tube '15 may be inserted therebetween, and by therrotation of the "rollers, wind the tube through to the position For winding the, rollers alever is mounted upon the shaft by sleeve 25'which'is provided upon'the end with ratchet teeth 26. A ratchet collar '27 is'r'igidly-securedto the shaft 2O. The'sleeve25c'ontains a spring 28 which operates-at 'one end against the end of the sleeve, and at "the op- I posite end against the pin-.29 which isin serted through the sha'ft -20sothat the sleeve is normally held away from the bracketand the "ratchet teeth disengaged. When it-is *to be operated, the key "24 andsleeve 25 arepushed inwardly against the tension of the T oma- Such "tubes normally contain creamy or :pas'ty materials which are eXuded through the nipple 16 at which-may be secured to a wall, or other suppOrti ngs'truC- ture, with side brackets-or plates 18 extend orfkey 24" means of a andz23 are so placed,

right is erected,

Upon the back plate, a slotted tubular up with a follower 31 slidable therein. An arm 32 extends outwardly through the slot and is provided with a col lar 33. V The collar '33 engages about the discharge tube 34. Sa'id discharge tube is pro- 7 vided upon the underside of the arm 32,.With

a tapered cap 35 which fits over the nipple 16,

and the tube is also bent at right angles, as

shown more particularly at Figures 1, 5 and 6, and is providedatthe .endjwith aclosure. As shown at Figures 1 and 5, this closure comprises a weighted member 36, hinged at'37 so that when pressure is released, the weight will close the closure to protect the contents of the tube. Instead of employing a weight, a cover 36, as shown at Figure 6,'is hinged at 37 and'a spring 38 is employed for holding the closure; 36 yieldingly in closed position. r j I The follower'31'is also provided with a cord or cable 39 extending downwardly through the tubular upright 30, and wound about a drum 40,-journaled to the back plate 17 upon 40 is provided with a spring 42, tending to at all times exertstress upon the cable 39 so that the cap 35 is at all times held firmly 1n 7 engagement with the nipple 16.

Instead of forming the cap 35 circular in cross section, as shown at Figure 8, and indi- 'cated at Figure 1, it may assume other forms for co-actionwith delivery ends of collapsible tubeswhich assume other than acircular Instead of employing the key 24- and ratchet mechanism associated therewith for the actuation of the rollers, theshaft 20, will,-

in the modification shown in Figure 10, be provided with a pinion 43. A rack 44 will enand isprovided with a slot 45 sliding upona providedat the outer end of the rack'44as the opposite end. i r a Inoperation, of the type shown at Figure 1, the cap 35 will be raised by lifting the arm 32,,raising thereby the follower 31 and unwinding the cable 39 against the tension of,

the spring 42. \Vhen sufficientoclearance has been provided, 'thecollapsibletube will be;

introduced by inserting the bottom folded edge'betweenthe rollers 22 and'23, andthe cap 35' then allowed to assume itspositi'on upon the nipple 16 through the tension of the spring 42, cable39 and follower 31, Thethejournal 41. This winding drum fixed pin 46. =-A knob or other convenlent means for manipulation is key 24 will be manipulated in the only direction it will operate until the contents, of the tube have exuded from the nipple into the cap I through the delivery tube 34 and raised the closure 36 or 36'. Upon the release of the tension upon the key, theclosure 36 or 36 v .will close. 1

Instead, however, of employing the key as above outlined, may be employed by pushing inwardly on the knob47 ,in the direction indicated by the which will rotate the pinion 43 and arrow, therewith, the roller 22 to which it is attached. .The; requisite amount of rotation having been applied," pressure upon the knob '47 is released; By reason of theposition of attachment of the spring 48' with the rack 44, it will lift the rack 44 fromenga'gement with the pinion 43 and retract it 'to.the position shown at Figure 10,. In this position, the parts are arranged by a repetition of the action; 7 I V Of course, the
